 note = {application, Objectives In Removable Partial Dentures (RPD) exercises, we have made the rest seat and guide plane. Therefore, we made a new RPD plaster model of the lower premolar that is quadruple the size of the normal one, in order to make the purpose of this exercise clear and handy. Materials and methods We used normal plaster, paraffin wax, inlay wax and impression material for the duplicated models. We carved and arranged the plaster model of the lower premolar that is quadruple the size of the normal one. Then we made the base of the model for perfection. Results and consideration The new model was made by Nissin Dental Products, Inc. and it was called the C4-MM.P.25 model. We think that the new model's usability was improved, because we tried to downsize this model, making it small, light and handier than the old model. Therefore, dental students can identify the tooth axis, so they can do similar work to real laboratory work, and instructors are able to work more easily on teaching and management than they used to. In addition, we think that exercise times were much shorter than before. Conclusion The new model unites good design and handy operations, and also, under exercises and subsequent exercises, we can management and keep it easily.},
